Patent DE-3030872-A1 (DE)
Title: Over-ride mechanism for e.g. fluid control valve - has thermally-responsive actuator with shape memory effect spring having heater in hollow spring coils
Inventor: ROBERTSON ROBERT ARTHUR
IPC: H01H37/46
Filed: 1980-08-14
Abstract: The override mechanism comprises a member (6) which is adapted to be moved into an overriding condition, by a spring (12) located against a valve stem (9) but is normally held against such movement by an actuator (14) retaining the spring (12) in the compressed condition. The actuator (14) comprises a spring of shape memory effect material which when heated maintains an expanded configuration, to retain the spring (12). If the heating is discontinued, the actuator loses its stiffness and allows the spring (12) to expand and move the member (6). The shape memory effect material is formed as a spring having hollow coils within which an electrical heating wire (14B) is provided. In alternative embodiment the spring has solid coils and is encased in a heating sleeve.

Title: Margin control for typewriter - has digital encoder scale to fix margin position with photoelectric sensing
Inventor: KREUTZBURG FRANZ ING GRAD
IPC: B41J29/42
Filed: 1980-12-18
Abstract: The line printer or typewriter has a non-contact sensing system to control the print head in relation to the edge of the paper. The print head (3) is moved along a horizontal guide (4) across the surface of the paper (2). Margin settings are fixed by setting blocks (8,9) that move along a guide bar (7) carrying a linear encoding scale based upon an 8-bit code. The code is read by photoelectric sensors (10,11) and the digital code valves are transmitted to the microcomputer control unit (1). An alternative system utilises a belt driven encoder instead of the linear scale.

Title: Device for replacing an orifice plate fitted in a pipeline
Inventor: ESCHRICH HUBERT
IPC: G01F1/42
Filed: 1981-04-03
Abstract: The invention relates to a device for replacing an orifice plate fitted in a pipeline while the operating pressure in the pipeline is maintained. The orifice plate frame supporting the orifice plate is withdrawn from the flow cross-section and is moved into a sluice which can be separated from the flow cross-section by means of a shut-off element and from which the orifice plate frame is removed after pressure relief. Gear racks used hitherto for the transport of the orifice plate frame caused many difficulties and a substantial outlay. In contrast, a device according to the invention is characterised in that the lifting mechanism is a threaded spindle (20) which is held in a threaded bushing (32) and which can be driven by means of a rotational movement of the latter, and in that the lower end of the threaded spindle (20) is a component of a coupling which interacts with a coupling part formed on the orifice plate frame (14) and can be actuated by means of a rotational movement of the spindle (20). The invention furthermore extends to a novel design of the shut-off element as a roller body having a slot which is formed in the central area and through which the orifice plate frame is guided. This results in a substantial reduction in the technical outlay and simplified assembly and handling. <IMAGE>

Title: Method for dynamic time slot allocation of the organisation channel of cellular mobile radio networks depending on traffic volume
Inventor: MEIER WERNER
IPC: H04W16/06
Filed: 1981-07-30
Abstract: Mobile radio networks with cellular radio area division use an organisation channel, which is assigned to the radio cells by temporally offset time slots in time division multiple access, for connection set-up, connection monitoring and signalling procedures for the mobile radio subscribers. The time slots are intended to be allocated to the radio cells in optimum fashion for the radio cells, taking into account the traffic volume which varies through time. This is achieved with the aid of a subscriber management computer system, present in any case, which can also convert instantaneously unused speech channels as required into auxiliary organisation channels whose time slots are then available in addition. <IMAGE>

Patent DE-3139502-A1 (DE)
Title: Circuit for magnetically triggerable printing elements, such as for example printing needles, printing hammers or the like for printers, in particular for matrix printers
Inventor: TILTSCHER GERALD
IPC: B41J2/30
Filed: 1981-09-29
Abstract: Printing elements of this kind are held in a position of rest under spring force, and when an electromagnet is supplied with current they are propelled into the printing position with the spring force being overcome or utilised, the self-induction of the electromagnetic coil occurring during switching off being converted briefly into current heat. The frequency of the system consisting of the electromagnetic coil, a metallic magnetic core, a spring and a needle attached to the spring is, in conjunction with the design of the character matrix, directly proportional to the printing speed of the printer which can be achieved. In order to achieve a higher frequency of the printing needle or of a printing hammer in which in particular the self- induction voltage is reduced more quickly than hitherto so that short switching times can be achieved for the printing needle or for the printing hammer, it is proposed that the electromagnetic coil (L1) be connected, when switching off occurs, to a module (C1, V3, R2) which generates a phase shift of 90 DEG , the voltage polarity of said module being reversed in polarity with respect to the terminals of the electromagnetic coil (L1). With a view to also achieving a more rapid build-up of the magnetic field of the electromagnetic coil (L1) at the start of the cycle of the printing needle (2) or of the printing hammer (11), it is also proposed that when the electromagnetic coil (L1) is switched on said coil be connected to a voltage source with a voltage which is raised in relation to the operating voltage of the electromagnetic coil (L1). <IMAGE>

Patent DE-3148170-A1 (DE)
Title: Hollow-charge ammunition with push-out spacer pin
Inventor: LALLINGER GEORG
IPC: F42B12/10
Filed: 1981-12-05
Abstract: The invention relates to a hollow-charge ammunition (1), such as a projectile, missile or the like, having a hollow charge (3, 5) and a spacer pin (8) which can be pushed into the recess (4) of the hollow charge and which carries a percussion contact (10) at its head end. The spacer pin (8) can be pushed out of this pushed-in position in a guided manner from the recess (4) of the hollow-charge ammunition into an ignition position. For this, the rear end of the spacer pin (8) is connected to a gas-tight diaphragm concertina (13) which can be drawn coaxially into the recess of the hollow charge and which is connected by means of its outer circumference to the interior of the housing (2) of the hollow-charge ammunition. This gives rise to an outwardly closed-off space which is limited by the diaphragm concertina and the recess of the hollow charge. During the flight of the hollow-charge ammunition, dynamic pressure can be introduced into this space by way of air-inflow ports (11), with the result that the spacer pin is pushed forwards. The spacer pin is locked in the ignition position. The air-inflow ports for the dynamic pressure are preferably located in the head end of the spacer pin. <IMAGE>

Patent DE-3202135-A1 (DE)
Title: I-core laminate stack for electrical cores which are to be welded
Inventor: LEICHER HANS
IPC: H01F27/33
Filed: 1982-01-23
Abstract: The invention relates to transformers in which the electrical cores are connected by two welded seams. Since the welded connections of the two welded seams take place only at the points of the outer limbs between the I-core laminate stack and the E-core laminate stack, the stack of the centre limb can vibrate from the E-core laminate stack. The consequences of this are humming noises which have a disturbing effect on the environment. The object of the invention is to prevent these humming noises. To this end, one or more welded seams are fitted on the outer surface of the I-core laminate stack. At the same time, the I-core laminate stack is deformed such that it presses onto the E-centre limb end, and humming is hence prevented. A further possibility for preventing humming of the E-centre limb stack is for the I-laminates to be cut in a convex manner on their cut longitudinal edge, with a suitably large radius. This raised area produces a defined pressure of the I-core laminate stack on the end of the E-centre limb, which prevents humming of the same.
